DRAIN GATE.

Application filed May 19,

T0 aJZ "whom it may concern:

Be it known that I, EUGENE E. GRIMES, citizen of the United States, residing at Tiflin, in the county of Seneca and State of Ohio, have invented certain new and useful Improvements in Drain Gates, of which the following is a specification.

This invention relates to an improved drain gate for automobile radiators. water pumps, and engine crank cases, while the invention may also be used as an oil gauge for some types of motor vehicle engines such as a Ford, the invention having as one of its principal objects to provide a particularly simple and at the same time thoroughly etl'ective device of the character in dicated.

The invention has as a further Object to provide a device wherein the spout of the device will be normally closed by a spring pressed flap valve.

A further object of the invent-ion is to provide a device wherein the spout will be formed with a beveled mouth so as to insure tight closing of the valve as well as assist in flushing the spout of any sediment collected near the mouth thereof.

And the invention has as a still further object to provide a device wherein the spout will be formed near its mouth with an enlarged discharge chamber which will tend to reduce clogging of the passage through the spout.

Other and incidental objects will appear hereinafter.

In the drawing:

Figure 1 is a. top plan view of my improved drain gate,

Figure 2 is a side elevation of the device, and

Figure 3 is a longitudinal section taken medially through the device.

Referring now more particularly to the drawing, it will be seen that my improved drain gate comprises a tubular spout threaded at its inner end as shown at 11 for engagement in a suitable orifice in the object to be drained and provided with a wrench receiving boss 12. From a point medially thereof the spout is exteriorly tapered toward this boss, as shown at 13, the wall of the spout being, as shown in Figure 3, thickened toward the outer end of the spout. This increased thickness of thewall of the spout permits counterboring 1921. Serial No. 470,823.

thereof to define a discharge chamber 1 1: at the outer end of the spout, the axial passage 15 of said spout opening into said chamber at its inner end while the outer terminal of the spout is formed with a beveled mouth 16. The chamber 14 is provided so that, be ing larger in diameter than the passage 15, said chamber will assist in preventing the clogging of the passage by sediment deposits.

Upstanding from the spout near its forward end are spaced ears 17 and mounted to normally close the spout is a valve 18 provided near its upper end wit-h spaced rearwardly projecting ears l9 mating with the ears 17. Extending through these mating ears'is a pintle 20 swingingly connecting the valve with the spout. Seating flat against the inner side of the valve is a gasket 21 secured by a bolt 22 extending through the valve and the gasket. This gasket may be formed of rubber, cork or other approved material and is of a diameter to overlie the mouth 16 of the spout closing the spout at its outer end. As will be appreciated upon an inspection of Figure 3, the gasket may be readily renewed when necessary. Coiled around the pintle 20 is spring 23 one end of which bears against the upper side of the spout while the other end of said spring is disposed to coact with the upper end of the valve yieldably holding the valve closed so that the gasket- 21 will be pressed against the mouth of the spout for effectually closing the spout, the inclination of 'said mouth tending to insure tight closing of the valve as well as also assisting fluid flowing through the spout, when the valve is opened, in breaking up and dis lodging any deposits in the spout. Depending from the valve at its lower edge is a medially disposed thumb lug 2% by which the valve may be manually opened and this lug is provided with an eye through which a suitable element may be engaged for lifting the valve. It will accordingly be seen that I provide a particularly simple construction for the purpose set forth and, at the same time, a device which will prove entirely efficient in practical use.

Having thus described the invention, what is claimed as new is:

1. A drain gate including a spout having I a discharge passage and having its mouth beveled downwardly and outwardlyirom its upper side, a pair of upstanding ears on the spout adjacent its niouth, a flap valve having a pair of rearwardly projecting ears near its upper end, a pintle inserted through the ears whereby to pivot the valve to the spout in position to lie upon and over the beveled mouth, and a spring coiled around the pintle and housed between the ears and having its ends bearing respectively upon the upper side of the spout and the rear side of the valve.

2. A drain gate including a spout having .a discharge passage and having its mouth beveled downwardly and outwardly from its upper side, a pair of upstanding ears on 15 the spout adjacent its mouth, a flap valve having a pair of rearwardly projecting ears near its upper end, said ears being pivoted to the first-mentioned cars, a spring housed between the ears and having its ends bearing respectively upon the spout and the rear side of the valve, ano a lug depending from the valve, said lug having atrans verse opening through its end.

In testimony whereof I afiix my signature.
